If you think of it as its own game its pretty good, but if you think of it as a sequel... it just looks like they haven't even tried. You can't not go back to it, you're a Big Daddy, yet for the sake of damage reduction you may aswell be a Splicer. I wouldn't consider it a waste of money, since £21 isn't too bad, but you just can't help but wonder if they thought no-one would notice...
It just doesnt seem as grand as the 1st game. Don't get me wrong - I enjoyed playing it but it there wasn't much depth (ho ho) to the storyline and it felt like it was over way too soon. In summary:
Sitting there with there little needle, stabbing a corpse in the head while all around Splicers assault her protector and enemies fall to the ground with spears through there head and on fire...
